Problems solved by technology

[0003] However, the motors, transmission mechanisms, braking mechanisms, cooling systems, electric control systems, hydraulic systems, and lubrication systems in most existing electric transmission devices are all matched separately and arranged in a decentralized manner, without an integrated and integrated design Planning, the current integrated research is only biased towards the integration of simple motors and speed change mechanisms
Therefore, the existing electric transmission device has a series of problems such as poor integration, scattered layout, many connection interfaces, large occupation volume, heavy weight, inability to realize integrated hoisting, difficult installation, and low maintenance efficiency, which need to be solved urgently

Abstract

The invention discloses an electric-driven speed changing device integrating heat dissipation, lubricating and electrical-controlled brake. The electric-driven speed changing device comprises a motor,a speed changing mechanism, a braking mechanism, a radiator, an electric control system, a hydraulic system and a lubricating system, wherein the braking mechanism is arranged at the tail end of themotor; a braking mechanism output end housing at the end of the braking mechanism and a motor tail end housing are integrally formed; a motor output end housing on the motor and a speed changing mechanism input end housing are integrally formed; the hydraulic system comprises pumps and a fuel tank, wherein the fuel tank is arranged at the bottom of the speed changing mechanism; the lubricating system comprises a radiator; the pumps comprise a large pump and a small pump; the large pump is used for providing operating oil pressure for the speed changing mechanism and the braking mechanism; andthe small pump is used for supplying oil to perform heat dissipation and lubrication of parts. The invention aims to provide the electric-driven speed changing device integrating heat dissipation, lubricating and electrically-controlled brake, and the device has the advantages of being high in integrity, compact in structure, small in occupied space, low in manufacturing cost, convenient to disassemble, assemble and maintain, good in control characteristics, safe and reliable to work and the like.

Description

technical field [0001] The invention belongs to the technical field of electric transmission, in particular to an electric drive speed change device integrating heat dissipation, lubrication, electric control and braking. Background technique [0002] With the global energy crisis and air pollution becoming more and more serious, electric transmission technology is an important direction for the development of vehicle transmission technology. Electric transmission device is the core component of electric vehicle power and transmission system. The electric transmission has significant advantages in terms of quietness, energy recovery, and reduction of vehicle heat. [0003] However, the motors, transmission mechanisms, braking mechanisms, cooling systems, electronic control systems, hydraulic systems, and lubrication systems in most existing electric transmission devices are all matched separately and distributed, and there is no overall integration and integrated design.
